People have long recognized in their long life and medical practice that emotion is one of the important factors leading to disease. For example, when angry or extremely angry, people will feel dizzy and light-headed, and there are even many cases of death due to cerebral hemorrhage caused by anger. In “The Complete Chronicle of Yue”, Niugao was so excited by the capture of Jin Wu X that he died of laughter. We often see scenes where a person becomes incontinent due to extreme stress. I’m afraid the most familiar example of emotions curing diseases is “Fan Jin Zhongju”, these are typical examples of emotions and diseases. If a person suffers from mental stimulation for a long period of time, or is suddenly subjected to severe mental stimulation beyond what the individual’s physiology can regulate, it can lead to disease. Among breast diseases, breast pain caused by mastopathy is a typical emotional disease. In modern society, women, like men, are burdened with social and family responsibilities, and with the monthly menstrual flow, they are more prone to emotional fluctuations. Some of them are depressed for a long time due to hopeless promotion, family conflicts, difficulties in child discipline, etc. Some of them have fights with their husbands and vomit, or their family members have accidents, so they are irritable, nervous and grief-stricken. So what is the relationship between emotions and breast pain disorder? The mammary gland is a target organ for sex hormones and is subject to cyclical changes due to endocrine influence. Mood swings have a greater impact on endocrine changes and can cause instability in sex hormone levels. In this way, when a woman is in tension, irritability, anxiety and depression during her menstrual cycle, it can cause abnormal secretion of sex hormones, resulting in an increase in ovarian estrogen and a relative decrease in progesterone or abnormal estrogen receptor function, which can induce breast pain disorder when there is an absolute or relative excess of estrogen. Then, emotional regulation should be considered as a key measure to relieve and reduce the occurrence of breast pain. There is a Chinese saying that “a smile can make a decade less”. Keeping a good mind can make you happy, relaxed and open. Learn to get along well with all kinds of people, keep a sense of humor, don’t be surprised by chaos, learn to forgive others, have a few close friends, always cooperate with others and have fun, and maintain a high level of self-confidence.
